ABSTRACT OF THE DISCLOSURE An infants training device having a seat portion and usable selectively on a conventional toilet seat and upon its own supporting base structure. Locating means are provided on said seat portion for removably mounting and fixedly locating the device in operative position on said toilet seat and base structure. A receiving vessel is usable with said device when it is used on said base structure, and means are provided on said seat portion for locating said vessel in alignment with an opening formed in said seat portion.

This invention relates to a device for toilet training infants, and more particularly to a chair for toilet training infants.

It is an object of the invention to provide an infants training chair which can be removably mounted on a conventional toilet or which can employ its own supporting structure and receiving vessel and which, when used with its own supporting structure, permits the receiving vessel to be easily removed and remounted in operative position thereon. It is a further object of the invention to provide an infants training chair of attractive appearance which can be economically manufactured largely from molded components, which will afford comfort and safety to an infant, and which will afford a high degree of sanitation.

In accordance with one form of the invention, there is provided a chair frame having a seat portion adapted to rest on a conventional toilet seat and provided with a centrally disposed opening having a downwardly extending flange around its periphery. A second flange projects downwardly from the seat portion radially outwardly from said opening for engagement with the inner edge of the toilet seat opening. A generally Z-shaped bracket is slidably mounted on the lower face of the seat portion adjacent the rear thereof for reception under the inner edge of the toilet seat opening whereby said bracket and second flange act in combination to releasably retain the chair in a fixed position on a toilet seat.

A pair of panels project upwardly from the seat portion along the rearward portions of its lateral edges. Desirably, a transversely extending rod is connected to said panels adjacent the upper ends thereof to limit rearward swinging movement of a lid pivotally connected to the upper face of the seat portion on a transverse axis rearward of the opening formed in said seat portion and to support said lid in its raised position. Conveniently, a safety strap is received in slots formed in the seat portion for holding an infant on the chair.

As shown, our infants chair comprises a seat portion 15 conveniently formed as a plastic molding and having a downwardly projecting lip 16 extending across its arcuate front edge. An arcuate flange 18 concentric with the lip 16 projects downwardly from the seat portion immediately inwardly of the lip and is interconnected thereto by a plurality of arcuately spaced braces 19. A second flange 20 concentric with the flange 18 and having an arcuate extent substantially the same as the flange 18 projects downwardly from the seat portion 15 inwardly of the flange 18. The flange 20 projects downwardly below the extent of the flange 18 and is provided with a pair of downwardly projecting ears 22 arcuately spaced on the flange 20 on opposite sides of the longitudinal center of the seat portion.

A pair of side panels or projections 24 project up- Wardly from the lateral edges of the seat portion adjacent the rear end thereof to provide a pair of confining side members to help hold an infant on a chair. Each of said panels comprises an inner wall 25 connected to an outer wall 26 by a top wall 27, rear wall 28, and forward wall 29. The rear walls 28 are generally vertically oriented, and the front walls 29 slope forwardly with their forward lower ends blending into the upper face of the seat portion 15. As shown in FIG. 4, the panel rear walls 28 terminate forwardly of a generally planar tongue 32 projecting outwardly from the rear edge of the seat portion 15.

An enlarged opening 34 is formed in the seat portion adjacent the center thereof. At its forward end, said opening is provided with a forwardly projecting arcuate extension 35 having a pair of laterally spaced inwardly directed shoulders 36 adjacent its connection to the main portion of the opening 34. The edges of the opening 34 are defined by a downwardly projecting flange 38 extending around the periphery of said opening and its extension. Desirably, the flange 38 has a depth greater than the flange 20 but less than the cars 22. A cup-shaped rearwardly open splash guard 40 is adapted to be carried in the extension 35. As shown, said splash guard comprises an arcuate upper portion 42 projecting above the scat r, J portion and connected to an arcuate lower portion 44 by an offset shoulder 45 adapted to seat against the flange 38 at its interconnection to the upper face of the seat portion 15. The lower end of the guard portion 44 terminates in an upwardly open hook 46 receivable under the lower edge of the flange 38. The guard portion 44 has a radius of curvature slightly larger than the radius of curvature of the extension 35 whereby the splash guard can be press-fit in the extension 35 with its hook 46 received under the flange 38 and its rear edges abutting the shoulders 36 for thus releasably bindingly retaining said splash guard in a rearwardly open operative position.

Rearwardly of the opening 34, the seat portion 15 has an aperture-d boss 50 projecting downwardly from its lower face and fitted with a threaded insert 51. A pair of transversely extending guide ribs 52 are disposed forwardly and rearwardly of the boss 50 with their lower ends coplanar with the lower end of said boss. A pair of forwardly and rearwardly extending guide ribs 54 are disposed on opposite lateral sides of the boss 50 and have their lower ends projecting downwardly below the bottom of said boss. A Z-shapcd bracket comprising a rearwardly directed leg 55 interconnected by a vertical web 56 to a forwardly directed leg 57 is connected to the boss 50 by a screw 58 extending upwardly through an elongated slot 59 formed in the leg 57 for reception in the insert 51. In mounting the chair on a conventional toilet seat 60, the flange 18 rests on the upper face of the seat and the flange ears 22 are received against the edge of the seat opening. The rearward portion of the chair is supported by the tongue 32 resting on the seat 60. The bracket leg 55 is received under the seat and acts in combination with the cars 22 for releasably retaining the chair in a fixed position on said seat. By sliding the leg slot 59 fore and aft on the screw 58, the fore and aft positioning of the leg 55 can be adjusted for mounting the chair on different size seats. These longitudinal sliding movements of the slot 59 on the screw 58 are guided by the ribs 54 engaging the lateral edges of the bracket leg 57.

Desirably. the chair is provided with a lid 62 conveniently formed as a plastic molding. Said lid has a cross-sectional extent greater than the cross-sectional extent of the opening 34 and its extension 35 and a width less than the spacing between the inner walls 25 of the panels 24. A pair of rearwardly projecting extensions 64 are formed on the rear edge of the lid 62, and each of said projections is provided with an inwardly extending pin 65 rotatably carried in an upwardly projecting ear 66 formed on the upper face of the seat portion 15 to define a transverse pivot axis for swinging movei ment of the lid from a closed position overlying the opening 34 to a raised position to which it projects rearwardly and upwardly from the chair. It is to be understood, of course. that the splash guard must be removed before the lid can be moved into its closed position.

In order to limit the rearward swinging movement of the lid and to support it in its raised position, a transversely extending rod 68 extends across the rear of the chair. As shown, the ends of said rod are bent forwardly as at 69 and then outwardly as at 70. The rod ends are received in openings 72 formed in the side panel rear walls 28. Immediately below the plane of the openings 72, the inner faces of the inner and outer panel walls 25 and 26 are provided with inwardly projecting abutments 74 which act in combination with the opening 72 for supporting the rod in a rearwardly projecting operative position on the chair. The rod is further retained in position by plugs 75 carried in the openings 72 between the rod and stretches 69 and the panel outer walls 26. With the rod 68 being disposed rearwardly of the lid axis formed by the pins 65 and ears 6-6, the lid can be swung over center to its raised position, and the rod 68 will support it in said raised position.

Conveniently, a pair of slots 76 are formed in the seat portion 15 within the fore and aft extent of the side 4 panels 24. A safety belt 77 is carried in the slots 76 with its free ends projecting upwardly through said slots for fastening around an infant sitting on the chair.

The training chair show in FIGS. 1*5 can also be mounted on its own supporting base and provided with its own receiving vessel so that it need not be employed with a conventional toilet. The supporting structure shown in the embodiment illustrated in FIGS. 6-9 comprises a groundengaging base 80 connected at its upper end to a bowl 82 having an inwardly directed lip 83 extending around its forward end and the forward portions of its lateral sides. Said bowl has an open rearward end and is provided with a floor 84 having an enlarged opening 85 formed therein. An upwardly projecting rear wall is formed on the bowl 82 and comprises a transversely extending front panel 86 terminating at its upper end in a rearwardly extending top wall 87. The panel 86 and wall 87 extend transversely of the bowl and at their lateral ends terminate in forwardly projecting panels 88 provided with front walls 89. The panels 88 have a width corresponding to the width of the chair side panels 24, and the bowl panel front walls 89 are angled slightly forwardly so that the side panels 88 and 24 can be brought into aligned abuttting relationship. It is to be understood, of course, that in using the chair shown in FIG. 4 with this supporting base, the lid rod 68 will be removed from the chair. The lid 62 will still swing rearwardly about the axis of the pins 65 and cars 66, but will be supported in its raised position by the rear wall panel 86.

The chair illustrated in FIG. 4 can be mounted on the bowl 82 by inserting the chair tongue 32 into a transversely extending, forwardly open channel 90 in the rear wall panel 86. The channel supports the rear portion of the chair on the bowl with the chair side panels 24 abutting, and being continuous with, the bowl side panels 88. The forward portions of the chair are sup ported on the bowl by the chair lip 16 resting on the bowl lip 83. The flange 18 engages the inner edge of the bowl lip 83 for locating the forward portion of said chair on the bowl and then retaining the tongue 32 in the channel 90.

A receiving vessel 92 is supported on the bow] floor 84 in vertical alignment with the opening 34 and its extension 35. As shown in FIG. 8, the bottom of the vessel 92 is provided with an annular rib 94 adapted to abut the forward edge of the opening 85 in the floor 84. The upper end of the vessel has a diameter slightly larger than the fore and aft extent of the opening 34 and its extension 35 so that the flange 38 will project downwardly into the open upper end of the vessel 92. Thus, the flange 3-8 and the floor opening 85 act in combination to locate the vessel 92 in vertical alignment with the chair opening 34 and its extension 35. Conveniently, an outwardly projecting rim 95 is formed on the upper end of the vessel 92.

Still another modified form of the supporting structure for the chair is illustrated in FIGS. 10-14. In this embodiment, the chair is supported on a pair of laterally spaced leg frames 10!]. Each of said leg frames is identical in construction and comprises a ground-engaging stretch 101 continuous at its forward end with a rearwardly angled front leg 102 projecting upwardly between the inner and outer walls 25 and 26 of the adjacent chair side panel 24. The leg 102 is at the same general rearward inclination as the side panel front wall 29 to abut the inner face of said wall, and its upper end is angled further rearwardly to provide an upper horizontal stretch 103 adapted to abut the lower face of the side panel by wall 27. An offset 104 is formed on the leg 102 within the extent of the side panel 24 to abut the inner faces of the panel walls 25 and 26 to bindingly retain said leg within the side panel. The rear end of the ground engaging leg stretch 101 is continuous with an upwardly and forwardly directed rear leg 105 which projects upwardly into the side panel 24 against the forward face of the rear wall 28. Within the vertical extent of the side panel, the rear leg 105 is also provided with an offset 106 bindingly received between the inner faces of the panel walls 25 and 26.

In this embodiment, as contrasted to the embodiment shown in FIGS. 69, the lid retaining rod 68 is employed for limiting the rearward swinging movement of the lid 62 about the axis of the pins 65 and ears 66. As described in connection with FIGS. 1-5, the ends 69 and 70 of said rod are received in the openings 72 in the rear walls 28. The assembly of the rod on the chair differs slightly with this supporting structure than the assembly of the rod on the chair seat when the supporting structure is not employed as shown in FIGS. 1-5. With this supporting structure, the plugs 75 are not employed and the out-turned rod ends 70 are received around the upper ends of the rear legs so that the rod ends are interposed between the leg 105 and the abutments 74 and the upper ends of the leg 105 are confined between the rod ends 70 and the rear wall 28.

The vessel 92 is supported in operative position below the opening 34 with the forward portion of its rim 95 resting on a pair of brackets 108 mounted on the flange 20 in arcuately spaced relationship. Each of the brackets comprises a front leg 109 interconnected by a web 110 to a rear leg 111. Inwardly and downwardly struck tongues 112 are formed on the bracket legs 111 to pierce the inner face of the flange 20 for bindingly retaining said brackets thereon. The upper end of each of the rear legs 111 terminates in an inwardly projecting finger 113 extending inwardly under the vessel rim 95 for supporting the forward portion of the vessel. The rear portion of the vessel rim 95 is supported on the forwardly extending leg 57 of the bracket mounted on the seat portion by the screw 58. Thus, the vessel is supported on the brackets 108 and the bracket leg 57, in operative position immediately below the opening 34 with the flange 38 projecting downwardly into said vessel. To remove the vessel from the chair, it is merely necessary to slide the bracket leg 57 rearwardly with its slot 59 riding on the screw 58 and the ribs 54 guiding said sliding movement. When the leg 57 has cleared the rear edge of the rim 95, the front portion of the vessel can be slid off of the bracket fingers 113 and said vessel can be removed from under the chair. Conversely, to mount the vessel in operative position, it is merely necessary to dispose the forward portion of the rim 95 on the bracket fingers 113 and then slide the bracket leg 57 forwardly to rest under the rear portion of said rim.
